FAQs

The timeline of your project will depend on the scale and scope of work. Once we understand your vision, we’ll work with you from the outset to set expectations with a detailed timeline to help you plan ahead.

Depending on the scale and type of work involved, you might not have to move out. We'll make every effort to keep you comfortable and minimise disruptions while we complete the work.

Many renovations in Sydney require approval, depending on the project’s scope. Smaller internal works may be exempt, while extensions, second-storey additions, or structural changes often require formal approval. We’ll guide you through the process and manage all required documentation with your local council.

A renovation typically involves updating or reconfiguring existing spaces, while an extension adds new areas, such as an extra bedroom, living zone, or second storey. We’ll take you through all the options and help you decide which will best meet your lifestyle needs and budget.

We engaged Daniel and his team at Firmus to complete our pool decking.We were so pleased with the service he provided. His communication was great, he solved many unforeseen problems and provided efficient solutions.He attend when he said and did the work in a timely manner. His work is clean and we were satisficed with the result.Highly recommend!
Daniel and his team have been so fantastic to work with. Due to management requirements, construction work had to be undertaken out of business hours with our specific request that we have no downtime in our usual schedule. Daniel went above and beyond, helping us move large pieces of furniture well into the evening on a Friday night and all through the weekend, liaising with management and all-involved parties, keeping us informed at all times. All communication and invoicing was discussed beforehand and clear. Trades were efficient and tidy. Daniel possesses that rare combination of transparency, honesty, time-consciousness, client loyalty, eye for detail, intelligence and emotional intuition which is rarely seen, let alone in the construction industry.

Firmus Building provided solid advice, delivered a good quality product and their contractors turned up daily to complete work in a timely manner. As they put the roof on quickly when the weather turned, our construction was completely water proof and the contractors could continue with putting in fixtures and fitting. Job well done!
